Yes, I agree. If you want to mix & match, then individual conversions are the way to go.

I also do them, but I do them manually (magnets & morphbrush), because I dont trust conversion software. That way, I can keep texture stretching and other issues to a minimum.

I did my figure conversions mostly just for heck of it. Hybrids are actually a lot easier. Lol.

But let's be honest: I guess 99% of the remaining Poser users would want a LaFemme that natively could wear G8/G9 clothes.

If I wanted to earn some $$$ and could figure out how to get a working G8/G9 rig into Poser (And bypass copyright problems), that's where I'd start. ;-)
